OPENING DEVICE FOR DOORS, GATES, AND THE LIKE.

Specification of Letters Patent.

Application filed December 27, 1915. Serial No. 68,737.

To all whom it may concern:

Be it known that I, J ESSE S. WENTWORTH, a resident of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Opening Devices for Doors, Gates, and the like, of which the following is a specification.

My invention relates to improvements in means for opening and closing doors, gates, windows, transoms or anything of like nature, and has for its object, the provision-of a door, gate, window, transom or'like device, which is disposed in a vertical position when closed and is swung to a substantially horizontal position when opened.

A further object of this invention is the provision in connection with devices of the character specified, of operating means including levers for swinging the gate door or other device through the arc of a circle to and from its vertical and horizontal position.

Further objects include the detail of construction and arrangement, whereby a device of this character is provided which operates simply and efficiently.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be defined in the claims, reference being had to the accompanying drawing which shows merely for the purpose of illustrative disclosure, a preferred embodiment of my inventive idea, it being understood that various changes may be made in practice within the scope of the claims without digressing from my inventive idea.

In the drawings, Figure 1 represents a vertical section through a door, constructed according to my invention, shown in closed position; Fig. 2 represents a similar view showing the door in open position; Fig. 3 is an inside elevation showing the door closed.

My invention includes broadly a gate arranged so as to assume a vertical position when closed and having an arrangement of supporting and operating levers whereby it may be moved to its open horizontal position and also being provided with an operating or controlling lever, pull cord or similar operating means. While it is designed to be applied primarily to the construction of new doors, still the invention is readily applicable to doors or other devices already inuse, without the necessity of material reconstruction or rearrangement. Its attachment to doors, windows, or other devices, is very readily and simply accomplished.

Referring now to the drawings, the numeral l designates the frame of the door or window within which the.door or window 2 v fits. This device 2 is arranged so as to assume a vertical position when closed and a horizontal position when opened. The de vice is mounted to swing 'on the hinge rod or link 3 which is pivotally connected to ears 4 and 5 as shown, the ear 4 being positioned adjacent the upper end of the door or window 2 and the ear 5 being located at a distance to the rear of the door frame of about one-half the height of the door. It

Patented Apr. 4,1916;

is to be understood that I provide a pair of these hinge rods or links 3, one on each side of the door. I also provide a pair of front hinge rods or links 6, which are pivotally connected to the ears 7 secured to the lower portion of the door and also to the extending brackets or arm members 8, which are secured to the frame of the door or window. The links of these bracket'or arm members 8 may be varied according to the length of the hinge rods or links 3.

I illustrate two forms of operating means for this device both of which include the knuckle joint or link connection which is formed by links 9 and 10, the former being pivoted to the hinge rods or links 3 at 11 and the latter being pivoted to the bracket or ear 12. These links 9 and 10 are pivoted together as at 13 and have connected thereto at this point, the link 14 which passes to the connecting link 15 which is pivoted to the operating rod 16, this rod being pivotally mounted on the ear or bracket 17. Or in lieu of this lever and operating rod connection, I provide the flexible means 18 which is connected to the links 9 and 10 at their pivotal point 13 and extends over the pulleys 19 and 20 to the grip 24;. To assist in the operation of the device I provide the arms 25 on links or rods 3 which may be counterweighted as shown at 26 or provided with the equivalent spring.

The dotted lines indicate the path of movement of the gate to and from its open and closed position, and it is therefore seen, that I have provided a structure which may be operated in various ways to move the gate from its closed vertical position through the arc of a circle to its open horizontal position. This movement is readily accomplished either by means of the flexible connection or the operating rod connection, and when the door or window is in its open position, it is out of the way and takes up a minimum amount of space.

What I claim is 1. In a mechanism of the character described, including in combination a stationary support, a member having a normal vertical position, hinged members pivotally connecting the upper end of said first mentioned member to the stationary support, other hinge members pivotally connecting the lower end of said first mentioned member with said stationary support, said other hinge members being shorter than said first mentioned hinge members, and an operating means connected to said first mentioned hinge members for moving said first mentioned member from its normal vertical position to a horizontal position and vice versa.

2. In a mechanism of the character described, including in combination a stationary support, a member having a normal vertical position, hinged members pivotallyw connecting the upper end of said first mentioned member to the stationary support, other hinge members pivotally connecting lower end of said first mentioned member with said stationary support, said other hinge members being shorter than said first mentioned hinge members, and an operating means connected to said first mentioned member from its normal vertical position and vice versa to a horizontal position, said operating means including a knuckle link connection.

3. In a mechanism of the character described, including in combination, a stationary support, a member having a normal vert tical position and adapted to be moved to a horizontal position, a pair of hinge members pivotally connected to the upper end thereof and to said stationary support, another pair of hinge members pivotally connected to the lower end of said first mentioned member and to the stationary support at a point about midway between the ends of said first mentioned member when in its normal vertical position, said other pair of hinge members being approximately one-half as long as said first mentioned hinge members, and extending at an angle toward said first mentioned hinge members, a knuckle link connection with said first mentioned hinge member, and operating means connected with said knuckle link so as to move said first mentioned member.

4. In combination, a member having a normal vertical position, a pair of rods on either side of said member for moving the member from its vertical position to a horizontal position, corresponding rods of each pair pivoted at fixed points at theii lower ends and inclined normally upwardly toward the member and pivotally connected thereto, the other and corresponding rods of each pair pivoted at fixed points at their upper ends and inclined normally downwardly toward the member and pivotally connected thereto, means for oscillating a pair of corresponding rods, whereby the member may be elevated from a vertical position to a substantially horizontal position and vice versa, such movement inverting the rods normally inclined downwardly toward the member from such position, to a substantially vertical position.
